Article Preview

The combined process which consisted of a four-stage contact baffled reactor followed by a five-stage plant filter bed was used to treat domestic wastewater. The start-up of the four-stage contact baffled reactor was investigated, and the efficiency of the combined technology treating domestic wastewater was studied. The results indicated that the four-stage contact baffled reactor which inoculated with anaerobic sludge could be started up in 52 d, and the proper hydraulic residence time was 24 h; when the four-stage contact baffled reactor was running stably, its average CODCr removal efficiency was 57.0%, and in the four-stage contact baffled reactor, the average CODCr removal efficiency of each stage was decreased gradually, which were 45.8%, 11.1%, 6.8% and 3.3%, respectively; when the influent CODCr was 276-370 mg/L, the effluent CODCr of the combined technology was 73.0-90.7 mg/L and the average CODCr removal efficiency of the combined technology was 75.0%.
